Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).. Iron ore is the source of primary iron for the world's iron and steel industries.

North America is a leading producer of coal, used in energy production; bauxite, used to create aluminum; iron and copper, both used in construction; and nickel, used to create steel, which North American companies export around the world. Gold and silver mines operate in …

The Titaniferous iron ore, sometimes massive, but usually in the form of dark black sand washed down from the rocks in the country around, is very plentiful in some parts of North America, New Zealand, &c., and is often associated with gold, gems, heavy metallic compounds, &c.

Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.

The American Iron and Steel Institute 2018 Profile is a comprehensive overview at the North American steel industry and shows why steel is—and must remain—the backbone of our nation's economy and a fundamental aspect of our everyday lives.

Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people's attention and they are denser than most other rocks.

Iron Beginnings in America One of the first things in which the colonists were interested in the New World were extractable metals. For the Spanish, gold and silver could be easily "extracted" from the Aztec and Incan civilizations, and the early English and French colonists hoped for similar riches when they arrived in America.

Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance.

Iron ore refers to rocks or minerals from which metallic iron is extracted for commercial use. These minerals appear dark grey to rusty red in color, and are usually rich in iron oxides. Iron occurs in these ores in the form of such chemical compounds as hematite, magnetite, siderite, limonite, or geothite.

Iron ore occurs in the form of rock from which the metallic iron is the final product. The bulk of these rocks are either Hematite or Magnetite, and it makes almost 98% of the iron ore produced worldwide that goes into making steel .
